We analyze the dynamics of a class of $\mathbb{Z}_{2n}$-equivariant differential equations of the form $\dot{z}=pz^{n-1}\bar{z}^{n-2}+sz^{n}\bar{z}^{n-1}-\bar{z}^{2n-1}$, where z is complex, the time t is real, while p and s are complex parameter

The existence and spatio-temporal patterns of $$2\pi $$ -periodic solutions to second order reversible equivariant autonomous systems with commensurate delays are studied using the Brouwer $$O(2) \times \Gamma \times \mathbb Z_2$$ -equivariant degree

We consider the Lienard differential systems Open image in new window in \(\mathbb {C}^2\) where F(x) is an analytic function satisfying \(F(0)=0\) and \(F'(0)\ne 0\). Then these systems have a strong saddle at the origin of coordinates. It has been

First we characterize all the polynomial vector fields in $\R^4$ which have the Clifford torus as an invariant surface. After we study the number of invariant meridians and parallels that such polynomial vector fields can have in function of the degr

This is a survey on the Darboux theory of integrability for polynomial vector fields, first in Rⁿ and second in the n-dimensional sphere Sⁿ. We also provide new results about the maximum number of invariant parallels and meridians that a polynomi

We consider the Beris-Edwards model describing nematic liquid crystal dynamics and restrict it to a shear flow and spatially homogeneous situation. We analyse the dynamics focusing on the effect of the flow. We show that in the co-rotational case one

We analyze the dynamics of a network of electrically coupled, modified FitzHugh-Nagumo (FHN) oscillators. The network building-block architecture is a bidimensional squared array shaped as a torus, with unidirectional nearest neighbor coupling in bot

Circadian rhythms in mammals are controlled by the neurons located in the suprachiasmatic nucleus of the hypothalamus. In physiological conditions, the system of neurons is very efficiently entrained by the 24-hour light-dark cycle. Most of the studi

Adenylyl cyclase (AC) is a prototypical cell-signaling molecule expressed in virtually all organisms from bacteria to man. While C1b, a poorly conserved region within mammalian AC, has been implicated in numerous isoform-specific regulatory propertie
